FBI details Columbine-obsessed suspect's activities before death

ROUGH CUT (NO REPORTER NARRATION) Denver FBI Special Agent in Charge Dean Phillips on Wednesday said authorities in Miami had alerted Colorado officials to Sol Pais' suspicious activity before a mass police search and her eventual death by a self-inflicted gunshot wound.

Phillips said she was considered a credible "threat" after she flew to Denver and procured a weapon.

The 18-year-old woman the FBI had described as "extremely dangerous" and "infatuated" with the Columbine massacre was reportedly found dead on Wednesday, after a massive police serach.

More than 400,000 Denver-area students were told to stay home from school after reports that Pais had flown from Miami to Denver on Monday, and bought a pump-action shotgun and ammunition, three days before the 20th anniversary of the Columbine massacre.
